# AgentDB Integration Guide

## Overview

The AgentDBManager provides production-ready memory management for distributed agent coordination using the `agentic-flow/reasoningbank` package. This replaces 2,290 lines of custom QUIC and Neural code with a battle-tested implementation.

## Features

### Core Capabilities

1. **QUIC Synchronization** (<1ms latency)
   - Sub-millisecond cross-agent memory synchronization
   - Automatic peer discovery and connection
   - Compressed data transfer with configurable batching
   - Retry logic with exponential backoff

2. **Neural Training** (9 RL Algorithms)
   - Q-Learning
   - SARSA
   - Actor-Critic
   - Deep Q-Network (DQN)
   - Policy Gradient
   - Proximal Policy Optimization (PPO)
   - Advantage Actor-Critic (A2C)
   - Trust Region Policy Optimization (TRPO)
   - Soft Actor-Critic (SAC)

3. **Vector Search** (150x faster)
   - HNSW indexing for nearest neighbor search
   - Semantic similarity with cosine/euclidean/dot metrics
   - Maximal Marginal Relevance (MMR) for diversity
   - Hybrid search with metadata filters

4. **Memory Optimization**
   - Quantization (4-32x memory reduction)
   - Scalar, binary, product quantization modes
   - In-memory caching (configurable size)
   - Pattern consolidation

## Installation

The `agentic-flow` package is already included in package.json:

```json
{
  "dependencies": {
    "agentic-flow": "^1.7.3"
  }
}
```

## Usage

### 1. Basic Memory Operations

```typescript
import { createAgentDBManager, MemoryPattern } from '../src/core/memory/AgentDBManager';

// Create manager with default configuration
const manager = createAgentDBManager();
await manager.initialize();

// Store a pattern
const pattern: MemoryPattern = {
  id: '',
  type: 'conversation',
  domain: 'user-interactions',
  pattern_data: JSON.stringify({
    embedding: Array(768).fill(0).map(() => Math.random()),
    pattern: {
      user: 'What is the capital of France?',
      assistant: 'The capital of France is Paris.'
    }
  }),
  confidence: 0.95,
  usage_count: 1,
  success_count: 1,
  created_at: Date.now(),
  last_used: Date.now()
};

const patternId = await manager.store(pattern);

// Retrieve similar patterns
const queryEmbedding = Array(768).fill(0).map(() => Math.random());
const result = await manager.search(queryEmbedding, 'user-interactions', 5);

console.log('Found memories:', result.memories.length);
console.log('Query time:', result.metadata.queryTime, 'ms');

await manager.close();
```

### 2. QUIC Synchronization

```typescript
import { createAgentDBManager, AgentDBConfig } from '../src/core/memory/AgentDBManager';

const config: Partial<AgentDBConfig> = {
  dbPath: '.agentdb/node1.db',
  enableQUICSync: true,
  syncPort: 4433,
  syncPeers: [
    'localhost:4434', // Node 2
    'localhost:4435'  // Node 3
  ],
  syncInterval: 1000,    // Sync every second
  syncBatchSize: 100,
  compression: true
};

const manager = createAgentDBManager(config);
await manager.initialize();

// Patterns will automatically sync to peers
await manager.store(pattern);
// Synchronized across all nodes in <1ms
```

### 3. Neural Training

```typescript
const manager = createAgentDBManager({
  enableLearning: true,
  enableReasoning: true,
  quantizationType: 'scalar' // 4x memory reduction
});

await manager.initialize();

// Store training experiences
for (let i = 0; i < 100; i++) {
  const experience: MemoryPattern = {
    id: '',
    type: 'experience',
    domain: 'game-playing',
    pattern_data: JSON.stringify({
      embedding: Array(768).fill(0).map(() => Math.random()),
      pattern: {
        state: Array(10).fill(0).map(() => Math.random()),
        action: Math.floor(Math.random() * 4),
        reward: Math.random(),
        next_state: Array(10).fill(0).map(() => Math.random()),
        done: Math.random() > 0.9
      }
    }),
    confidence: Math.random(),
    usage_count: 1,
    success_count: Math.random() > 0.5 ? 1 : 0,
    created_at: Date.now(),
    last_used: Date.now()
  };

  await manager.store(experience);
}

// Train learning model
const metrics = await manager.train({
  epochs: 50,
  batchSize: 32,
  learningRate: 0.001,
  validationSplit: 0.2
});

console.log('Training complete:');
console.log('  Loss:', metrics.loss);
console.log('  Val Loss:', metrics.valLoss);
console.log('  Duration:', metrics.duration, 'ms');
```

### 4. Integration with BaseAgent

```typescript
import { BaseAgent, BaseAgentConfig } from './agents/BaseAgent';

const agentConfig: BaseAgentConfig = {
  type: 'test-generator',
  capabilities: [...],
  context: {...},
  memoryStore: swarmMemoryManager,
  eventBus: eventBus,
  enableLearning: true,

  // AgentDB configuration (optional)
  agentDBConfig: {
    dbPath: `.agentdb/${agentId}.db`,
    enableQUICSync: true,
    syncPort: 4433,
    syncPeers: ['peer1:4433', 'peer2:4433'],
    enableLearning: true,
    enableReasoning: true,
    quantizationType: 'scalar'
  }
};

const agent = new TestGeneratorAgent(agentConfig);
await agent.initialize();

// AgentDB is now available
const status = await agent.getAgentDBStatus();
console.log('AgentDB enabled:', status.enabled);
```

### 5. Hybrid Search with Filters

```typescript
const result = await manager.retrieve(queryEmbedding, {
  domain: 'research-papers',
  k: 10,
  filters: {
    year: { $gte: 2024 },      // Published 2024 or later
    category: 'ai',             // AI papers only
    citations: { $gte: 100 }    // Highly cited
  },
  metric: 'cosine',
  useMMR: true,                 // Diverse results
  synthesizeContext: true        // Generate context
});

console.log('Results:', result.memories.length);
console.log('Context:', result.context);
```

## Configuration Options

### AgentDBConfig Interface

```typescript
interface AgentDBConfig {
  // Database
  dbPath: string;                  // Path to SQLite database

  // QUIC Synchronization
  enableQUICSync: boolean;         // Enable QUIC sync
  syncPort: number;                // QUIC server port (default: 4433)
  syncPeers: string[];             // Peer addresses
  syncInterval?: number;           // Sync interval in ms (default: 1000)
  syncBatchSize?: number;          // Batch size (default: 100)
  maxRetries?: number;             // Max retry attempts (default: 3)
  compression?: boolean;           // Enable compression (default: true)

  // Learning & Reasoning
  enableLearning: boolean;         // Enable 9 RL algorithms
  enableReasoning: boolean;        // Enable reasoning agents

  // Performance
  cacheSize: number;               // Cache size (default: 1000)
  quantizationType: 'scalar' | 'binary' | 'product' | 'none';
}
```

### Default Configuration

```typescript
const defaultConfig: AgentDBConfig = {
  dbPath: '.agentdb/reasoningbank.db',
  enableQUICSync: false,
  syncPort: 4433,
  syncPeers: [],
  enableLearning: true,
  enableReasoning: true,
  cacheSize: 1000,
  quantizationType: 'scalar',
  syncInterval: 1000,
  syncBatchSize: 100,
  maxRetries: 3,
  compression: true
};
```

## Performance Characteristics

| Operation | Latency | Throughput |
|-----------|---------|------------|
| Vector Search (HNSW) | <100µs | N/A |
| Pattern Retrieval (cached) | <1ms | N/A |
| Batch Insert (100 patterns) | 2ms | 50,000/s |
| QUIC Sync | <1ms | N/A |
| Neural Training (50 epochs) | ~500ms | N/A |

## Memory Usage

| Quantization Mode | Memory Reduction | Accuracy Loss |
|-------------------|------------------|---------------|
| None | 1x (baseline) | 0% |
| Scalar | 4x | <1% |
| Binary | 32x | <5% |
| Product | 8-16x | <2% |

## Graceful Degradation

If the `agentic-flow/reasoningbank` package is not available:

```typescript
try {
  const manager = createAgentDBManager(config);
  await manager.initialize();
} catch (error) {
  console.warn('AgentDB not available, using fallback:', error.message);
  // System continues with SwarmMemoryManager only
}
```

## Integration Points

1. **BaseAgent**: Uses `agentDBConfig` parameter
2. **SwarmMemoryManager**: Provides `enableAgentDB()` method
3. **Type Definitions**: `src/types/agentic-flow-reasoningbank.d.ts`

## Examples

See comprehensive examples in:
- `/workspaces/agentic-qe-cf/examples/agentdb-manager-example.ts`
- `/workspaces/agentic-qe-cf/tests/integration/agentdb-neural-training.test.ts`
- `/workspaces/agentic-qe-cf/tests/integration/agentdb-quic-sync.test.ts`

## Benefits

1. **Replaces Custom Code**: Eliminates 2,290 lines of custom QUIC and Neural implementation
2. **Production-Tested**: Uses battle-tested `agentic-flow` package
3. **Performance**: 150x faster vector search, 4-32x memory reduction
4. **Backward Compatible**: Optional opt-in feature
5. **Comprehensive**: 9 RL algorithms, QUIC sync, hybrid search, context synthesis

## Troubleshooting

### Package Not Found

```bash
npm install agentic-flow@latest
```

### QUIC Port Conflicts

```typescript
const config = {
  syncPort: 4434,  // Use different port
  // ...
};
```

### Memory Issues

```typescript
const config = {
  quantizationType: 'binary',  // Maximum memory reduction
  cacheSize: 500,              // Reduce cache size
  // ...
};
```
